The health care provider may detect a new heart murmur, or a change in a previous heart murmur. Examination of the nails may show splinter hemorrhages.
|
 |
Doctors begin the diagnosis by taking a history, asking the patient about the symptoms mentioned above. During a physical examination , the doctor may also uncover signs such as fever, an enlarged spleen, signs of kidney disease, or hemorrhaging. ...

An electrocardiogram (ECG) is a test that records the electrical activity of the heart. See also: Holter monitoring; Stress test.
|
|
Electrocardiography is a commonly used, noninvasive procedure for recording electrical changes in the heart. The record, which is called an electrocardiogram (ECG or EKG), shows the series of waves that relate to the electrical impulses that occur...
|
|
The electrocardiography unit, also called an electrocardiograph, is an apparatus that indirectly measures the heart's electrical activity and records it as a graphic tracing.
|
|
The electrocardiogram (ECG) displays important information about the heart, including the occurrence of a heart attack or lack of oxygen, whether conduction of the heartbeat is disturbed, or its rate or rhythm altered. It is useful as a rapid indi...

|
During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with ha...

The health status of populations and of individuals is assessed for many reasons. Assessing needs for care helps guide the allocation of resources— diagnostic assessments guide treatment, prognostic assessments contribute to planning, and assessin...

Transesophageal echocardiography is a diagnostic test using an ultrasound device that is passed into the esophagus of the patient to create a clear image of the heart muscle and other parts of the heart. A tube with a device called a transducer is...
|
|
Transesophageal echocardiography (TEE) is a diagnostic test in which an endoscope with an ultrasound transducer at its tip is inserted into the patient's esophagus by means of a catheter (thin tube). Sound waves are transmitted and received by the...
|
 |
An echocardiogram is a test that uses sound waves to create a moving picture of the heart. The picture is much more detailed than a plain x-ray image and involves no radiation exposure.
|
 |
Echocardiography is a diagnostic test that uses ultrasound waves to create an image of the heart muscle. Ultrasound waves that rebound or echo off the heart can show the size, shape, and movement of the heart's valves and chambers as well as the f...

A blood culture is a laboratory test to check for bacteria or other microorganisms in a blood sample. Most cultures check for bacteria. A culture may be done using a sample of blood, tissue, stool, urine, or other fluid from the body. See also: Br...
|
|
A blood culture is done when a person has symptoms of a blood infection, also called bacteremia . Blood is drawn from the person one or more times and is tested in a laboratory to find and identify any microorganism present and growing in the bloo...
|
|
A blood culture is a lab test designed to detect the presence of bacteria , yeast, or fungi in the bloodstream. A routine blood culture involves injecting a sample of the patient's blood into two bottles of sterile nutrient broth (one for aerobes ...
|
|
Fever evaluation tests, better known as febrile agglutinins tests, are performed to detect the presence of antibodies in the blood that are sensitive to temperature changes. Antibodies are proteins produced by the immune system in response to spec...
|
|
The sedimentation rate test, also called the erythrocyte sedimentation rate (ESR) or sed rate test, measures the speed at which the red blood cells (erythrocytes or RBCs) separate from the liquid part of the blood (plasma) and settle to the bottom...
|
|
ESR stands for erythrocyte sedimentation rate. It is a test that indirectly measures how much inflammation is in the body. However, it rarely leads directly to a specific diagnosis.
|
|
The erythrocyte sedimentation rate (ESR), or sedimentation rate (sed rate), is a measure of the settling of red blood cells in a tube of blood during one hour. The rate is an indication of inflammation and increases in many diseases.

Ultrasound involves the use of high-frequency sound waves to create images of organs and systems within the body.
|
|
Ultrasonography is a diagnostic technique that involves directing high frequency sound waves at tissues in the body to generate images of anatomical structures. Ultrasonography is also called sonography, diagnostic sonography, and echocardiography...
|
|
A thyroid ultrasound, or sonogram, is a diagnostic imaging technique used to evaluate the structure of the thyroid gland . The thyroid is an endocrine gland, which means that it releases its secretions directly into the bloodstream or lymph. It co...
|
|
Ultrasonography is the study of internal organs or blood vessels using high-frequency sound waves. The actual test is called an ultrasound scan or sonogram. Duplex ultrasonography uses Doppler technology to study blood cells moving through major v...
|
|
The use of ultrasound to obtain diagnostic images is referred to as diagnostic sonography. Since diagnostic sonography utilizes a nonionizing form of energy, there are no known bioeffects. Thus, diagnostic sonography is applied to a large spectrum...
|
 |
Diagnostic medical sonography, or ultrasound, is a technique using high frequency sound to create images of specific areas of the body to diagnose various pathologies. The diagnostic medical sonographer performs examinations, records anatomic cond...

A complete blood count (CBC) test measures the following: The number of red blood cells (RBCs; The number of white blood cells (WBCs; The total amount of hemoglobin in the blood; The fraction of the blood composed of red blood cells (hematocrit; T...
|
 |
One of the most commonly ordered clinical laboratory tests, a blood count, also called a complete blood count (CBC), is a basic evaluation of the cells (red blood cells, white blood cells, and platelets) suspended in the liquid part of the blood (...
|
 |
A complete blood count (CBC) is a series of tests used to evaluate the composition and concentration of the cellular components of blood. It consists of the following tests: red blood cell (RBC) count, white blood cell (WBC) count, and platelet co...
|
|
The clinical laboratory test that evaluates the three main cellular components of peripheral blood (red cells, white cells, and platelets) is called the "complete blood count" (CBC). It is used commonly to assess whether a patient is anemic (low r...
